Description

Provide a clear and concise description of the requested feature/capability.
From NCO SPA: During the HAFS v1.0 code stability test, to recompile HAFS code with ‘-check all’ and ‘-ftrapuv’ flag, or using "-check bounds" only.

The code stability test of exec/hafs_vi_split.x and exec/hafs_vi_anl_combine.x failed in "-check bounds". Please investigate this failure and address it at the next upgrade.

Here are the detailed info -

@ChuankaiWang-NOAA, could you please work with @BijuThomas-NOAA to reproduce this issue and then address this issue? Thanks!

An uninitialized variable was found in the WNLSM.f90.
Two uninitialized variables were found in the anl_combine.f90.
The VI process completed successfully with debug built (-check all -ftrapuv) after initializing those three variables.
Both results from the new codes and the results from the original codes are identical.
The updated codes were in the hafsv2_baseline_nco branch.
